LOL..... probably best, I've only tried the moon a couple of times and never been happy with the results. Need some serious kit to get anything good and I'm not there.

You can always browse the images on the NASA site - we will never be able to beat those.

Shot at maximum aperture too! Very nice work.

How do you like your Tamron 200-500? I find mine a little difficult to use - I consider myself lucky if I get a shot thats's in focus when using it.

Mark turned me on to http://www.opanda.com/en/iexif/index.html. It's a freeware browser plug-in and system extension that displays the EXIF data.

The EXIF data shows the actual focal length to be 500mm, but the 35mm equivalent focal length on his Sony A100 to be 750mm. A 1.7x converter on the Beercan would only give you an actual focal length of 357mm.
Hmmmm, interesting. How did you come up with 357mm?

I thought that the beercan at 210mm x 1.5 (digital camera) = 315mm x 1.7 tcon would = 535mm.
Did I miss something somewhere?

210 with a 1.7 TC = 357mm real focal lenth. Multiply by the Sony 1.5 crop factor for an equivalent focal length of 536mm.

The actual focal length of the lens he used to take the shot was 500mm. The actual focal length of the Beercan with your 1.7x converter is 357mm.

The crop factor doesn't affect the actual focal length. It's a crutch for people familiar with 35mm film cameras and lenses so they can associate the field of view they are acustomed to with the field of view of lenses on digital cameras with their smaller image size. Since we're comparing two situations where images are or would be created with the same dSLR, adding in the crop factor disguises what's actually happening. If we were comparing two images, one created on a Sony A100 and the other created on an Olympus E-330, we would need to account for the effect of the E-330's smaller image sensor by applying the applicable crop factors, but that is not the case here.

FrankDThanks, I took about 50 shots to get that ONE. The 200-500 is a lens you need alot of practice with. A tripod is almost a must with this lens. Spot metering and high ISO also a must when moon shooting.

You can get a closer shot if you stand on the roof:|
